At 78 and having always worn briefs type underpants I decided that perhaps I would try boxers. I tried pairs from a well know High St store and also from a well know brand of boxers. Neither provided... See more

About Crossfly
Written by the company
Crossfly was created to redefine everyday comfort for men. For too long, men have settled for outdated designs and average-quality underwear, while women’s underwear has evolved with innovation, support, and premium fabrics. We’re here to level the playing field — with performance-driven, intelligently designed products that put comfort first.
Born from a small team of UK and US sportswear professionals with decades of experience in product innovation and marketing, Crossfly was created with a simple mission: to elevate men’s everyday comfort through intelligent design, premium quality, and sustainable thinking.
We’ve poured our expertise into creating a lifestyle brand that puts performance, durability, and comfort first. Our underwear and socks aren’t just everyday essentials — they’re your go-to, must-have gear that supports you through work, sport, travel, and everything in between. With every Crossfly product, you’ll feel the difference from the moment you put it on.
What Sets Crossfly Apart?
Unmatched Comfort: Our Cocoon internal pocket system offers all-day support, eliminates friction, and keeps you cool — so you can focus on life, not discomfort.
Innovative Design: The X-Fly reimagines the traditional Y-front with a faster, smarter, one-handed access system that just makes sense.
Premium Fit: Our ZeroFold360™ Waistband moves with your body and stays smooth — no rolling, no digging, just pure comfort.
Feel-Good Products in Every Way We don’t launch anything unless it improves on what came before. That means using superior materials that feel better and last longer than the competition. And where possible, we choose sustainable options, from responsibly sourced fabrics to 100% recyclable packaging. Because looking after the planet is part of feeling good, too.
Our Vision: Take Comfort to the Extreme Whether you're pushing limits or just getting through a long day, Crossfly is designed to move with you, support you, and make you feel great doing it. Once you’ve worn Crossfly, you won’t want to go back.

Great from start to finish
The whole shopping experience from selecting the products, though to the checkout was slick and easy, delivery was fast and the items are of great quality. I’ve already placed another order

Poor design and customer service
The website shows a picture of the "coccoon pouch" with 2 golf balls gently held in the pouch. But when I tried the boxer briefs on, the "golf balls" were nowhere near the pouch. The pouch was way too low to be of any benefit, and I am a fairly average guy. So I decided immediately to return them. I sent a message and got back a reply to mail the package, but there was no return label, as promised in the written policy. So I had to request the mailing label, which I did receive. I mailed the package on 10/7 and it was delivered on 10/9. But there was no acknowledgement of receipt, and as of today, 10/17, I have not gotten any correspondence acknowledging receipt and have not gotten a refund.
Addendum 10/18- After sending a complaint, I did get a note from Crossfly that I will be getting a refund.

Excellent high quality comfortable…
Excellent high quality comfortable boxers. Yes I paid the same price for one pair that I'd normally pay for three pairs but the comfort of the fabric, the design of the fly are unmatched! I will definitely be investing in some more of these. You don't actually feel like you're wearing boxers when you have these on. The fabric is so soft and flexible and very comfortable. I didn't know if I'd use the fly feature as sometimes when standing up to pee when wearing trousers it can be a bit difficult to undo a zip and then try and use the fly feature, with other boxers, but this system works a treat. They also stay nice and fresh throughout the day. Yes they cost the same as a 3 pack of Ted Baker boxers on eBay, but I think they will last longer, wash up better and remain comfortable (i.e. not shrink in the wash!)

Love this underwear
Love this underwear. Bought one pair. Then two more and have now signed up to their regular subscription package. Super comfy pouch for your plums but the clever fly is what sells it for me. Rather than being a fight or a tangle to get to your bits, it just works. The drip-guard fabric is a bonus and the fabric is super soft. If I sound like I work for the company, please note that I don’t, I just really love their product!

And don’t worry, you definitely don’t sound like you work here — just like someone who truly appreciates comfy, well-designed underwear! 🩲💛 Thanks for joining the subscription family and for sharing your experience. We promise to keep delivering comfort (and clever fly😉) every month!

5 star Undies
I’m a bit of an underwear aficionado, so was looking forward to trying these out. They fit great, look good on, give good support. The material feels good, soft against the skin and washes well. The fly is practical, I wish all trunks came with a fly as good as this. Delivery was speedy and I’ll definitely be ordering more in the near future.
